1 UNISONIC TECHNOLOGIES CO., LTD U2429 SERIAL DATA CONTROL DUAL ELECTRONIC VOLUME DESCRIPTION The UTC U2429 is a dual channel electronic volume controlled with 2-wire serial data. The built-in reference circuit can compose of an electronic volume with less external parts. DIP-8 FEATURES * Built-in reference circuit * Control with serial data Volume 0 ~ -83dB (1dB/step), - (Independent control is allowed in each channel) * Low noise and low distortion VNO = 5µVrms (ATT = - ) THD = 0.01% Typ. (V0 = 0.5Vrms) SOP-8 ORDERING INFORMATION Ordering Number Lead Free Halogen Free Package Packing U2429L-D08-T U2429G-D08-T DIP-8 Tube - U2429G-S08-R SOP-8 Tape Reel MARKING DIP-8 SOP-8 1 of 6 Copyright 2015 Unisonic Technologies Co., Ltd
